             Summary: ClusterMapReduceTestCase does not clean directories
                 Key: MAPREDUCE-7320
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-7320
             Project: Hadoop Map/Reduce
          Issue Type: Bug
            Reporter: Ahmed Hussein


Running Junits that extend {{ClusterMapReduceTestCase}} generate lots of 
directories and folders without cleaning them up.

For example:
{code:bash}
men test -Dtest=TestMRJobClient{code}
generates the following directories:
{code:bash}
- target
   -+ ConfigurableMiniMRCluster_315090884
   -+ ConfigurableMiniMRCluster_1335188990
   -+ ConfigurableMiniMRCluster_1973037511
   -+ test-dir
        -+ dfs
        -+ hadopp-XYZ-01
        -+ hadopp-XYZ-02 
        -+ hadopp-XYZ-03
{code}
